do any of you use sponge sanding blocks and are they as good as sandpaper. I saw them at lowes and they are priced the same as a pack of sandpaper. On the back they say they last longer but do they thanks Mike

I use them for various applications. They last a decent amount of time and can be washed and such. Get mine from HF usually. Not the very best but they get the job done. Still use sandpaper though, somethings just require it.

I have a few and never use them. I like plain old sandpaper with either the Preppin' Weapon blocks or, for finer work, these blocks from Veritas. If I need to get into moulding or other curves, I use rubber profile blocks.

I’ve used quite a few of them. They don’t cut as well as real sandpaper but for sanding between coats of primer, paint and clear costs I think they are great and easily conform to profiles.

I rarely use them except to clean up rust on cast iron, they are really good for that.

They’re great for profiles.

They’re awesome for sanding on the lathe or drill press for round parts. Buy them from Harbor Freight as suggested above. They come in 8 packs and they are way cheaper than Lowes or HD.

I find that they really don’t last any longer than sand paper so i rarely use them on flat surfaces but they conform well to weird shapes so they are very useful for that.

As always, have fun,

Mike, if you do get some and start using them, do not apply too much pressure as the will start disintegrating. Otherwise, I’m like several other posters, have some, rarely use them…............. Jerry (in Tucson)

I use them extensively, but only for certain applications. The quality is all over the place. For quick flattening of a finish, I’ll use the more rigid blocks. They clog up as fast as sandpaper, but can be cleaned with compressed air. For final finish sanding the cheaper “soft” blocks (actually pads) work quite well. The grit seems finer than their rating (i.e.. 180 grit acts like 220).

Overall they are invaluable for curves and hard to access areas.

I have used them occasionally but not real often, mostly in flat work for rounded corners when I didn’t want to grab a pad sander. Like some, the quality seems to vary a lot. On the lathe I do use the rubber pads (about the thickness of a mouse pad) with psa backed paper for straights and gentle shallows or long beads. For details on the lathe it may be difficult to sand evenly. The ones I have are thick enough that to apply enough pressure to sand around a bead you would be sanding the top much more than the sides, same for a cove. For beads or coves I use the standing strips without a pad so that it can be used down in the beads or coves.
I have used a rigid backer on the lathe for long straight sections such as areas on a wand.

I wet sand with them and use them for other than flat surfaces. To me they wear out fast for as much as they cost.
